Two stones are through up simultaneously from the edge of a cliff 240 m high with initial speed of 10 m/s and 40 m/s respectively. Which of the following graphs best represents the time variation of relative position of the second stone with respect to the first? Assume stones do not rebound after hitting the ground and neglect air resistance, take . ` g= 10 m//s^(2) ` (The figures are schematic and not drawn to scale)

Two stones are thrown up simultaneously from the edge of a cliff 200 m high with initial speeds of 15 m s^(-1) and 30 m s^(-1) respectively. The time variation of the relative position of the second stone with respect to the first is shown in the figure. The equation of the linear part is

Two stones are thrown up simultaneously from the edge of a cliff with initial speed v and 2 v . The relative position of the second stone with respect to first varies with time till both the stones strike the ground as.

One stone is projected horizontally from a 20 m high cliff with an initial speed of 10 ms^(-1) . A second stone is simultaneously dropped from that cliff. Which of the following is true?

Two stones are thrown vertically upwards simultaneously from the same point on the ground with initial speed u_(1) = 30 m//sec and u_(2) = 50 m//sec . Which of the curve represent correct variation (for the time interval in which both reach the ground) of (x_(2) - x_(1)) = the relative position of second stone with respect to first with time (t) (v_(2) - v_(1)) = the relative velocity of second stone with respect to first with time (t). Assuming that stones do not rebound after hitting.

A projectile is fired form the top of a 40 m high cliff with an initial speed of 50 m/s at an unknown angle. Find its speed when it hits the ground.

Two stones A and B are projected simultaneously from the top of a 100 - m high tower. Stone B is projected horizontally with speed 10 ms^-1 , and stone A is droppd from the tower. Find out the following : (a) Time of flight of the two stone (b) Distance between two stones after 3 s (c ) Angle of strike with ground (d) Horizontal range of particle B .

A man standing on the edge of a cliff throws a stone straight up with initial speed (u) and then throws another stone straight down with same initial speed and from the same position. Find the ratio of the speeds. The stones would have attained when they hit ground at the base of the cliff.

A stone released with zero velocity from the top of a tower, reaches the ground in 4s. The height of the tower is (g = 10 m//s^(2))

A ball is thrown upwards from the top of a tower 40 m high with a velocity of 10 m//s. Find the time when it strikes the ground. Take g=10 m//s^2 .
